Car-seat.

ESSINGTON N. GIL ILLAN, or CHICAGO, ILLINOIS, ASSIGNOR TO THE- WIIEELER'COMPANY, OF ILLINOIS.

CAR-S EAT.

SPECIFICATION forming part of Letters Patent No. 675,368, dated May 28,1901.

Application filed April 2, 1900.

To aZZ whom it may concern.-

Be it known that I, ESSINGTON N. GILFIL- LAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inCar-Seats, of which the followingis a full, clear,and exactspecification.

My invention relates to that class of reversible car-seats in which theback may be shifted forward and back for changing the facing direction;and it has for its primary object to pivot the back-supporting arms at apoint near the floor and at the same time prevent such arms frompartaking of the full inclination that would naturally follow fromshifting them the distance necessary for changing the facing directionof the back, thus also preventing the back from being excessivelyinclined when in position for use.

With these ends in view myinvention consists in certain features ofnovelty in the construction, combination, and arrangement of parts bywhich the said objects and certain other objects hereinafter appearingare attained, all as fully described with reference to the accompanyingdrawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1: is a side ele-v vation of my improvedseat, showing one end of the frame removed or cut off. Fig. 2 is a frontview thereof with one end of the seat broken away, and Fig. 3 is adetail side elevation of the mechanical movement by means of which theposition of the back is controlled.

1 represents the end frames of the seat, which are connected together byhorizontal tie rods or bars 2 3 and which in my invention are employedas substitutes for the usual sills upon which the rockers of theseat-cushion 4 rest and slide as the facing direction of the back 5 ischanged.

6 represents back-supporting arms, which are shown in the form of plainbars extending upwardly into suitable sockets in each end of the back,as usual, or in any suitable way, and which arms are located between theends of the cushion 4 and the frames 1 and have their lower endsprovided with floating pivotal supports having a limited movement, sothat when the back is thrown over from Serial No. 11,077. (No model.)

side to side the arms 6 will not only make a pivotal movement, but willalso shift bodily in the direction of the throw. This floating pivotalsupport consists of a pair of parallel arms 7, pivoted at 8 to portionsof the frame members 1 at their lower ends, while their upper ends arepivoted at 9 to a cross-bar 10, to which latter the arm 6 at each end ofthe seat is pivoted. For the purpose of bringing the pivotal point ofthe arm 6 near the floor while providing for a wide range of lateralmovement for it the cross-bar 10 has a lug 11 dropped down from itsunder side, and on the lower end of this lug is carried the pivot 12'forthe arm 6. The pivotal movement or oscillation of the arm 6 is limitedby stops 13, projecting from the inner sides of the end frames 1 on bothsides of the seat, and at or near each end of the cross-bar 10 is a lug14, against which the arm 6 strikes when the back is shifted, and thuscauses the parallel arms 7 to shift from side to side.

With the described construction it will be seen that when the back isthrown from side to side its first movement will be a pivotal one solelyon the pivot 12, which will continue until the arm strikes one of thelugs 14, whereupon the arms 7 will move with the arms 6, carrying thepivotal support 12 in the direction of movement of the back and cansingthe back-supporting arms to move bodily until they strike one of thestops 13, thus giving the back the requisite throw without compelling itto partake of the angle of inclination that would naturally follow ifthe arms 6 were supported on fixed pivots. In order that this movementmay also impart the desired shifting movement to the seatcushion, therockers of the cushion are provided with yokes or notches 15, in whichengage lugs 16, carried by upright levers 17, one of which is pivoted toa cross-bar 18 on each of the frames 1 and has a slot 19 in its lowerend, through which the pivot 12 passes, thus causing the seat-cushion toshift in the opposite direction to that in which the arms 6 are thrown.This is evident from the fact that when the upper end of arm 6 is thrownin one direction the upper end of arm 17, which is pivoted to bar 18between its connection with the arm 6 and seat-yoke 15, will be port andlimiting the independent motion of forced in the opposite direction, andsince the lug 16 on arm 17 is free to slide up and down in yoke 15 onthe bottom of the seat, but cannot move laterally without also movingthe yoke 15 with it, it follows that the seat-rockers 4 will becompelled to slide on their sills 2, but without lifting therefrom, adistance equal to the throw of the upper end of arm 17 and in adirection opposite to the movement of the back 5. The pivot 12 inconjunction with the pivoted arm 17 may also constitute means forlimiting the rocking movement of the arms 7, such movement being checkedwhen the pivot 12 reaches the bottom of the slot 19.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. In a reversible car-seat movement the combination of aback-supporting arm extending to a point contiguous to the floor, stopsfor limiting the throw of said arm, a floating pivotal support for thelower end of said arm, said arm having a limited motion independently ofsaid floating support, and means carried by said floating support forimparting the motion of said arm to said supthc back-supporting arm withrelation to said support, substantially as set forth.

2. In a reversible car-seat movement the combination of aback-supporting arm, a pair of pivoted arms connected together and towhich said back-supporting arm has pivotal support at a point below theupper ends of said arms and upon which pivotal support said back hasoscillatory motion independent-ly of said arms and means for limitingthe independent motion of said back-supporting arm with relation to saidpair of pivoted arms, substantially as set forth.

3. In a reversible car-seat movement the combination of aback-supporting arm, a pair of pivotal arms, a crossbar connecting saidpivotal arms and upon which cross-bar said back-supporting arm haspivotal support means for limiting the oscillation of saidbacksnpporting arm with reference to the seatframe and means forlimiting the oscillation of said baek-supportim, arm with reference tosaid pivotal arms, substantially as set forth.

4:. In a reversible car-seat movement the combination of aback-supporting arm, parallel pivoted arms, a cross-bar pivoted to saidparallel arms and havinga dependingsupport to which said back-supportingarm is pivoted, means for imparting the motion of said backsupportingarm to said parallel arms and means forlimiting the oscillation of saidbacksupporting arm, substantially as set forth.

5. In a reversible car-seat movement the combination ofa back-supportingarm extending to a point near the floor, a pair of upright pivotal armspivoted near the floor, a crossbar pivotally connecting the upper endsof said pivotal arms and to which said back-supporting arm is pivotallyconnected, lugs movable with said pivotal arms for limiting theindependentoscillation of the back-supporting arm with reference to thepivotal arms and means for limiting the motion of said back-supportingarm and pivotal arms, substantially as set forth.

6. In a reversible car-seat movement the combination of aback-supporting arm provided with a floating pivotal support, a seat, apivoted lever having operative relation to said pivotal support and alsoto said seat for shifting the latter in unison with the backsupportingarm, substantially as set forth.

'7. In a reversible car-seat movement the combination ofaback-supporting arm having a floating pivotal support, a shiftableseat,- and a pivoted lever having sliding connection therewith and alsosliding connection with said floating pivotal support, substantially asset forth.
